11.5 Sample Application
In the example below, the free-running timer is used to generate pulse outputs with a 50% duty
cycle and arbitrary phase relationship. The programming is as follows:
• The CCLRA bit in TCSR is set to 1.
• Each time a compare-match interrupt occurs, software inverts the corresponding output level
bit in TOCR (OLVLA or OLVLB).
